Invalid MEX-file 'fv_cache.mexa64': dlopen: cannot load any more object with static TLS #12

Hello, I want to try voc-realse 5.0, but when I run "pascal('bicycle', 3);", I encounter the following error:

Caching features cluster objective: 6285.721 cluster objective: 6285.721 cluster iter: 23/25 Invalid MEX-file '/home/jeremy/jWork/voc-dpm-master/bin/fv_cache.mexa64': dlopen: cannot load any more object with static TLS

Error in train (line 76) fv_cache('init', max_num, max_dim, max_nbls);

Error in pascal_train (line 71) models{i} = train(models{i}, spos{i}(inds), neg_large, true, true, 1, 1, ...

Error in pascal (line 62) model = pascal_train(cls, n, note);

can someone help me?

Same issue with me. Any solution so far?

I've found a workaround that fixed this error for me. I simply had to add the libraries which fv_cache.mexa64 depended on to my LD_PRELOAD path. You can check it's dependencies with this command

ldd /your/dpm/path/bin/fv_cache.mexa64

And then add any dependencies that are outputted. Example:

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libm.so.6

libm.so.6 was just one of the many libraries I had to add, you will probably end up having to add around 8 libararies to the path.

Once I did that, I restarted Matlab and the error no longer persisted.

I think that error has something to do with the hardware. Because Matlab is always loading libs and son there's no place for any more. When I train my own model using PC, it suffered the same problem as yours. But when I shift to a server, this error doesn't occur anymore.
